I agree totally that most will do fine without, but the parent comment cited the fact that few devs know about bytecode/jvm to support not knowing wasm. But descriptive statements don't imply prescriptive statements. So just because most have no clue, doesn't make it "right", or able to be used as justification.

I wouldn't call myself a Java dev - I mean I know Java like 99% percent of the world does - so I may have a terrible perspective on this anyways. Although knowing the basics of how Java source code -> running process would certainly help any Java dev.
